React Native vs Flutter: Choose Your Cross-Platform Mobile App Solution

React Native vs Flutter: Choose Your Cross-Platform Mobile App Solution

With the advent of technology, millions of people are using smartphones, and the smartphone has become one of the most reachable interfaces between business and customers. Thus, the increasing popularity of mobile apps is spreading swiftly and become compulsory for successful businesses. All sizes of businesses- a start-ups or an enterprise, have now interested to create their own mobile app to stands strongly in the market. As per the report by Statista, the global mobile app revenues amounted to above 365 billion dollars in the year of 2018. And, it is estimated that in 2023, mobile apps will generate more than 935 billion dollars in revenues.

Introduction of Cross-platform mobile solutions make the development of mobile apps quickly and cost-effective. But choosing the right technology framework is an essential factor for developing a new app.

The reason why cross-platform is popular for App development

Nowadays, many cross-platform solutions are available in the market and gaining popularity. It saves your time as well as develops an app within your budget. It leads to making many choices available for you. Flutter and React Native are the two leading market booster frameworks that can be the fundamental pillar of your mobile app development process.

Properties of cross-platform development

· Provide cost-effective within the budget solution

· Code reusability functionality

· Availability of Plugins

· Easy cloud integration

· Dependability in UI components

A small introduction of Flutter and React Native

React Native is an open-source framework started by Facebook in 2015. It efficiently combines both the Android and iOS platform’s native APIs. React Native uses JavaScript to build mobile apps and too much dependent on the third parties. The React Native framework should be installed using the Node Package Manager.

Flutter is a mobile application software development kit (SDK) started by Google in 2017. Flutter has rich in the development of APIs and UIs component, which helps to create accurate, well-performed, and fast mobile applications that can run on both the operating systems- Android and iOS. Flutter uses the Dart programming language.

Inherent differences between React Native and Flutter that enables you to choose the right one

Both React Native and Flutter are the on-demand examples of cross-platform frameworks. The comparison of both the cross-platform framework will help you to pick the most competent framework for your app.


When we compare the performance of React Native and Flutter, Flutter wins the battle. It uses profiling tools of Dart programming language- DevTools that helps the Flutter developers to visualize and explore Flutter widget trees. Also, in the Flutter, there is no JavaScript bridge between the device native components, therefore the speed of development, and running time automatically increases.

On the other hand, developing an app with React Native faces issues related to architecture, libraries, and native components.

Development time

Time taken in app development plays an essential role in the success of any technology. So choosing the technology that offers rapid app development, is an important task.

React Native maintains the largest USP components (ready to use components). Also, it has a hot-reloading feature facilitates quickly to review the changes in mobile UI that significantly reduces the app development time.

While in Flutter, you need to add separate files for both iOS and Android. It also provides a hot-reloading feature that helps to save time. But, when we compare both React Native and Flutter, React Native wins the race.

Stability & Flexibility

Stability and flexibility is another factor which needs consideration while developing a mobile app. When we compare React Native and Flutter, we found that React Native is an established framework that offers seamless user experience via direct communication with the native platforms and supported by the well-established tech communities.

Whereas, Flutter was trying to secure a reliable place in a highly competitive market before the release of its stable version in July 2019. But now things have changed, and Flutter has become worth investing that renders a rich set of customized widgets to build captivating experiences.

Language comparison

React Native allows developers to write code using Javascript and XML-Escape markup known as JSX that targets mobile platforms.

On the other hand, Flutter uses Dart for writing code. Dart language is easy to use and associated with modern features of multiple languages based on the OPPS concept.


During the application development process, documentation is a time-consuming process. Documentation via React Native framework is not organized and missed many things in the documentation process. Thus, developers take help from external sources.

Whereas, Flutter has an Integrated Development Environment (IDEs) and tool and compatible with a visual studio that adds value to the framework. So, to get the managed documentation, go with Flutter.

Lifecycle Management

React Native provide a better work environment that simplifies the app lifecycle by optimizing it as per requirement. But, in the case of Flutter, it only gives you the scope of working in stateless or stateful conditions.

Quick Comparison: React Native vs Flutter

Final Thoughts on Comparison

Here, in this blog, we have presented a detailed comparison based on the parameters that play an essential role in choosing the right technology for mobile app development. The above comparison lies on your preference whether you want to React Native for an interactive user interface and experience or Flutter for an excellent performance.

Hope the above blog will sort the doubts related to Flutter vs React Native. Both technologies reduce development time. And their libraries and ready-to-use components make it more efficient for building the mobile app.
